Bomber is a fun World War I arcade-simulation game. It is played in full screen sideway scrolling mode. It is "free" type of arcade game, meaning that you can fly in any direction you want. You finish level after all objectives described in briefing screen are accomplished, but you can accomplish them in any order or by using any means. You can bomb them (hence the title), destroy them with the machine gun, con enemy planes to crash into targets, or, if you are really desperate, go for kamikaze option.
You can get a number of bonuses depending on your type of play. For example, if you chose not to fire a gun (only using bombs), you get bomber bonus. There are 11 such bonuses.
